False advertising

Hi. I just bought a phone from sportscene in benoni Lakeside Mall. The phone is R9 LITE. According to the advert on the mobicel website and the brouchers . The phone is a dual sim card phone. To my surprise the phone is a single sim card. I tried calling the mobicel customer care, they can not help me. My question to them is why to they advertise the phone as a dual sim in which is not a dual sim.......This is false advertising and misleading. Now I am stuck with a phone that I did want. I wanted a dual sim phone.
